Actually, he is worse than those guys defensively. At his best, in BOS in a great system surrounded by All Defensive 1st and 2nd teamers, he was as bad defensively as Harris and Mudiay were in a shitty defense in DEN. Post injury, without the benefit of one of the top defensive coaches and systems in the league, he's worse than they are.
Of course, its a case of "What have you done for us lately". The most recent date is the most relevant. Until he proves he's recovered from his injury and is anywhere close too the same player he was pre-injury, in Boston's system, he's not.
There are 30 GMs in the NBA and not one of them thought he was worth more than a 1-year minimum salary contract. Those GMs have seen him play pre and post injury. Pre-injury there was talk of him as an MVP candidate and a max contract player. If one of those 30 GMs thought there was a chance he could come anywhere close to his pre-injury level of play, he would have gotten a lot more than a $2 million for 1 year.
So, their young players can only get better and ours can't? There is no guarantee that Jokic will ever be any better on defense. He's not going to suddenly gain lateral quickness. He's not going to suddenly become a high flying rim protector. If he had the potential to be either of those things, we would have at least seen flashes of it by now. We have two rim protectors in Nurk and Collins. Nurk is the same age as Jokic and Collins 3 years younger.
So, best case scenario for them (a 1-dimensional chucker, and unproven, injury prone rookie and one proven player who only excels on one side of the court) vs. worst case scenario for us (one 1st team All NBA player, a second proven 20+ ppg player, and none of Nurk, Collins, Simons or Trent Jr. have the potential to become better than Murray or Porter). I know you're trying to refute
@KingSpeed's silly super team narrative, but you've gone WAY overboard in the opposite direction.
